zack, that transmitter is part of a transceiver, the other part would simply be the receiver. :wink:
the trick is wiring them up to work togethor, which basically hooks both to the same antannae.
Now, that would be a very basic single channel transceiver, the more complex ones include multiple channels, channel guard, double or UP conversion to reduce noise, less bandwidth then FM radio, delayed AGC as well as auxillary AGC, squelch, and some type of noise limiter.
